To all 'whom 'it may concern:

Be it Aknown that I, ANTOINE Lavorx, al.

ciftizenfof France, residing at 7 Rue de Chteaudun, Paris, in theRepublic of f France, have invented new and usefulv linprovements 1nSpeed-Changing Gearing for Motor-Cars, of which the following is'a"specication.

,This vinyention relates to speed changing gearing formotor cars andconsists substantially` `in the use of a single shifting pinion whichcan be brought successively intoenv gagenient with anydesired number ofinternelly or externally toothed gears` of different diameters, thesmallest of which serves as a clutch `in the ca 'se of internallytoothed gears, the entiremec'hanism being mounted as a vvholein anindependent gear case or in a hollow'casing attached to the back axlestay. TheA accompanying drawings show by Way n of example one form ofspeed changing gearing according to this invention in which the shiftingpinion is adapted vto engage with internally toothed gears. Figure 1being a vert-ical section, Fig. 2 a horizontal' section thereof with theadjacent parts and Fig. 3 a cross section one line B B of Fig. l.

1 and 2 are a line of shafting with a universal coupling 3, forreceiving the power of the motor. The shaft l is carried in a bracket 9,adapted to oscillate and slide on a shaft 10. The shaft 1 carries at itsendd a pinion/i, which by suitable operation ontl the bracket 9 can bebrought into direct engagement either with externally or inter nallytoothed speed reducing` gears, 6, and 8, for ,forward travel, or intoengagement Withl the gear il for rearward travel. During the forwardtravel the gear. 8 actsa's a toothed coupling when in engagement withthe pinion and the gear 11 is drawn back by a spring 12 .or any'othersuitable means.

1'6" and 17. The end of. the box 14 may l drive a shaft operating thedriving axle, or itwmay carry directly aconical pinion 18 for tialloperating the 'differential as shown in the accompanying drawings, inthe cese of in# ternally toothed gear Wheels. f The improved speedchanginggean ha the following important advantages.: in creasedcihciency in transmitting oi the.

power of the motor is obtained by disponez A ing with intermediategears. There is alA most an entire` absence or weer, as'jthe gears worktogether with a very large number ofV teeth .in the case of internallytoothed gears..

The mechanism is simpler and greater ifa#n cility `is afforded fordisinonnting the parte. l Any desired innnber or speed reducing gearsaccording to the purposes for which 'the rehicle is designed., may beemployed. Withontf other complication.

Having new described my invention what l claim.' as new and desire tosecure by liet'-Y ters Patent, is: 1
